recreational impacts, and capital costs. A summary of these and other constraints was
compiled through numerous conversations with local, state, and federal agency personnel
and other parties with an interest in the Recovery Program. A description ofthe
constraints and their potential impacts on the Program's ability to control water
temperatures are provided in the report.

Modelin2: Recommendations. Based on the data analysis, we strongly recommend
modeling all 3 Aspinall reservoirs, using QUAL-w2, and a multi-variate statistical model
of Gunnison River temperatures. Stratification of Morrow Point and Crystal Reservoirs is
complicated by hypolimnetic inflows from Blue Mesa, and a mechanistic model is
needed to predict changes in stratification due to a TCD.
